Some Personal Reflections on Quantum Non-locality and the Contributions of John Bell

Published by on

Basil J. Hiley (University of London) Submitted to “Quantum Nonlocality and Reality – 50 Years of Bell’s theorem” I present the background of the Bohm approach that led John Bell to a study of quantum non-locality from which his famous inequalities emerged. I recall the early experiments done at Birkbeck with an aim to explore the possibility of `spontaneous collapse’,… Read more →

Weak Measurements, the Energy-Momentum Tensor and the Bohm Approach

Published by on

Robert Flack and Basil J. Hiley Forthcoming in S. Gao (eds.). Protective Measurements and Quantum Reality: Toward a New Understanding of Quantum Mechanics. Cambridge: Cambridge University Press (2014). In this paper we show how the weak values, <x(t)|Pμ|ψ(t0)>/<x(t)|ψ(t0)>, are related to the T0μ(x, t) component of the energy-momentum tensor. This enables the local energy and momentum to be measured using weak measurement techniques…. Read more →
